Meeting the Challenges Facing Wheat Production The Strategic Research Agenda of the Global Wheat Initiative

Wheat occupies a special role in global food security since, in addition to providing 20% of our carbohydrates and protein, almost 25% of the global production is traded internationally. The importance of wheat for food security was recognised by the Chief Agricultural Scientists of the G20 group of countries when they endorsed the establishment of the Wheat Initiative in 2011. The Wheat Initiative was tasked with supporting the wheat research community by facilitating col-laboration, information and resource sharing and helping to build the capacity to address chal-lenges facing production in an increasingly variable environment. Many countries invest in wheat research. Innovations in wheat breeding and agronomy have delivered enormous gains over the past few decades, with the average global yield increasing from just over 1 tonne per hectare in the early 1960s to around 3.5 tonnes in the past decade. These gains are threatened by climate change, the rapidly rising financial and environmental costs of fertilizer, and pesticides, combined with declines in water availability for irrigation in many regions. The international wheat research community has worked to identify major opportunities to help ensure that global wheat pro-duction can meet demand. The outcomes of these discussions are presented in this paper

New antecedents on the distribution and ecology of Botrychium dusenii (H. Christ.) Alston (Ophioglossaceae) associated with anthropogenic environments in the Coyhaique province, Aysen Region, Chile

Penailillo, P (Penailillo, Patricio). Univ Talca, Inst Biol Vegetal & Biotecnol, Talca, ChileConducting botanical and ecological explorations with the objective of studying the floristic composition of post-fire communities in the Aysen Region, we found new regional records of the fern Botrychium dusenii (H. Christ.) Alston (Ophioglossaceae). These findings, that extend the north limit of the species distribution, occurred in open areas affected by historical human-provoked fires (happening between 1950 and 1960) during the regional process of colonization

Vegetation of Patagonia

In this chapter, we describe the major phytogeographic provinces of Patagonia. Emphasis is placed on physiognomic vegetation formations, internal heterogeneity, and degree of anthropic disturbance. Main vegetation formations within provinces include temperate forests, steppes, moorlands, and shrublands. Internal plant heterogeneity is high in all provinces and is associated with climate, soils, altitude, and natural (e.g., volcanism) or anthropogenic disturbances. The most important anthropogenic disturbance varies among provinces in relation to vegetation formations. Domestic grazing is a widespread disturbance agentin steppes and shrublands, while oil and natural gas extraction may also cause disturbances affecting local plant communities in some areas. In contrast, clearing for agriculture and afforestation are common in temperate forests. Invasion of exotic plants and animals are also a threat for the conservation of pristine vegetation. Disturbances, together with the ongoing climate change, can strongly influence vegetation structure and functioning that in turn could affect populations of wild animals, particularly lizards.Fil: Bisigato, Alejandro Jorge.
